Nice post Hive account@cob but I would argue that individuals holding pegged assets will gain in case of scenarios resembling MtGox.
Assume Tether is getting crashed. This will cause all crypto including BTS to go down. When BTS goes down too fast it might cause Black Swan scenario. In worst case BitUSD holders will remain with BTS equivalents at the time of liquidating pegged asset. Most probably the downtrend movement of BTS will just get faster after Black Swan. In the end pegged asset holder is risking to have bags of BTS that is falling down together (if not more) with all the other crypto.
Of course all of the above is true in case of really serious negative events that will have the tremendous impact comparable to MtGox crash.
